19 Whisker from 3/27/2013¶
I chose some 90 sec z-band exposures Alistair took during the engineering night (3/27/2013) and measured the moments using the weighted moments with 2pix as the sigma of the weight kernel. These moments are used to generate the whisker plots. Then, to calculate the whisker/whisker rms, the moments are corrected for the weight kernel. The individual whisker plots are in the attached summary.pdf file. The data files corresponding to the following plot is in the desIQ_summary.txt.
